This does not fit the existing mount of my V6 AWD '08 Toyota Highlander, nor can the existing OEM cable attach. I spent about 90 minutes under the dash trying to figure out if I could run the cable from the new antenna to the radio -- not without an enormous amount of labor.
Does not fit -- "some modification" in their description apparently means drilling new holes through the firewall. Avoid unless you are pretty darn sure of what you are ordering.

Overall this was an easy install. Slight modification to mount to make a tight fit on fender. A large washer was sufficient to provide adequate pinch to the fender wall. Whip is adjustable to give proper angle once it is mounted. Had to get a female adapter to connect to existing cable (trunk mount) but Radio Shack had the necessary part and was easy to install. The only down side is the length of the antenna because it doesn't give maximum am reception. FM is fine. Overall, I have no complaints. Good product and works fine. Also product shipped in just a couple days after ordering it. Great service. Thank you.
